Cholera Toxin B Injection:

After adequate anesthetic depth was reached, a dorsal cut in the skin was made
just above the kidney, posterior to the last rib and lateral to the midline. Rat-toothed
forceps were used to pull the fat surrounding the adrenal gland out of the incision. Care
was taken to avoid grabbing the adrenal gland with the forceps.  Once the adrenal gland
was exposed, 10 µl of 1% CTB solution (List Biological Laboratories, Inc.) was injected
into the adrenal gland using a Hamilton Syringe (Hamilton Company). …
